我们提出了一种技术，以简化校准过程的双能量扫描，使用铝（AL）和塑料（PL）为基础材料。本质上，该方法确定了在所选能量下基础材料的“基函数”。该技术通过两个简单的一维校准步骤来代替繁琐的二维校准过程。此外，该技术还为解决双能问题提供了一种替代方法。
We present a technique to simplify the calibration procedure of the dual-energy scanning, using aluminum (AL) and plastic (PL) as basis materials. In essence, this method determines the "basis functions" of the basis materials at the chosen energies. This technique replaces the two-dimensional calibration procedure, which is tedious, by two simple one-dimensional calibration steps. In addition, this technique also provides an alternative approach for solving the dual-energy problem.
